> When we run secure datanode on IBM PowerPC with IBM JDK, the jsvc wrong with error
> {noformat}
> jsvc error: Invalid JVM name specified server
> {noformat}
> This is because of the  HDFS_DATANODE_SECURE_EXTRA_OPTS "-jvm server".
> For IBM JDK it is enough to run it without -jvm server.
> So I think we can check if IBM jdk in hdfs-config.sh before setting HDFS_DATANODE_SECURE_EXTRA_OPTS.
